# DESCRIPTION
#
# This macro searches for a GNU version of make. If a match is found, the
# makefile variable `ifGNUmake' is set to the empty string, otherwise it
# is set to "#". This is useful for including a special features in a
# Makefile, which cannot be handled by other versions of make. The
# variable _cv_gnu_make_command is set to the command to invoke GNU make
# if it exists, the empty string otherwise.

# * The variable `ax_cv_gnu_make_command` is set to the command to invoke
# GNU make by copying `_cv_gnu_make_command`, otherwise it is unset.
# * If GNU Make is found, its version is extracted from the output of
# `make --version` as the last field of a record of space-separated
# columns and saved into the variable `ax_check_gnu_make_version`.
